Calcite Powder

Pure calcium carbonate powder

Description

Calcite powder is a naturally occurring calcium carbonate (CaCO₃) mineral renowned for its exceptional purity, brilliant whiteness, and outstanding chemical properties. Due to its controlled particle size, high brightness, and superior hardness, it is a crucial raw material in numerous industries. In the plastics industry, calcite powder enhances polymer strength, improves surface finish, and reduces production costs. In paints and coatings, it provides better opacity, gloss control, and improved dispersion. The ceramics and glass industries rely on its high thermal stability and ability to enhance product durability. Additionally, calcite powder is extensively used in rubber, adhesives, sealants, and construction materials, where it improves mechanical properties and extends product lifespan. Its multifunctional applications make it an indispensable component in modern manufacturing and industrial processes.
